Painting & Decorating- 12 Feb 2019
He truly showed professionalism that I had struggled as a guest house operator to get from handy people. He would go out of his way to satisfy. The finished redecorated room project was a masterpiece and took a little longer than planned because of the weather but he gave it his all! I am pleased I took a chance on him as there was no review on his profile when I hired him. I would however, pay attention to work and point out issues as they come up otherwise, you will have dirt and rubbish to content with as the workers leave all the mess after work.

Extensions- 5 Nov 2016
Leslie carried out the following works: chemical damp injection to walls on rear extension, reroute down-pipe, repair fracture on rear wall, install gutter hedgehog. Hopefully, this will resolve some of the issues we had with damp, a blocked down-pipe and an overflowing gutter. Leslie arrived on time on the first day but was delayed a few hours the next day. However, the work still was done within two days as expected. Thank you!

We needed a rear extension built with an internal courtyard. From day one when we first contacted Mert to get a quote he was professional and easy to talk to. His quote was good value for money. During the job he and his team were approachable, careful with our property and always easy to talk to and answer questions we had. The work Mert did was fantastic and our neighbours have already gone on to use him. We will get him back again for more work and highly recommend him.

Had work carried out by RS construction recently, was an overall pleasant and stress-free experience, had a dormant chimney breast removed all the way through my property. Which had to be removed due to constant leaks and repairs by previous roofers. Ross was very helpful and knowledgeable throughout the project and his team kept my house and garden very clean considering the work that was undertaken, it has not only freed space within my property but given me peace of mind concerning continuous leaks, which have caused numerous issues over the years. Can't recommend this company anymore , from sale to completion a very professional and helpful service

Carpentry- 24 Jan 2021
George came to do up our hallway. He laid flooring and installed new spindles and a handrail on our stairs too. He did a wonderful job on the whole lot and we were very happy with him. We were awkward and changed our mind on the first laminate flooring that I had picked out online, he ripped it up and started again with the new flooring we picked and it was no hassle to him. George is a lovely fella, trustworthy and professional. Would highly recommend

Extensions- 6 Jan 2023
I am doing a double storey L shaped extension and the experience has been great so far. Vascontractors have been open, transparent, clear in communication. Have always understood the customer need. The quality of workmanship seen so far has been great be it building work, tiling, joinery or painting. Always provided a detailed timeline and schedule about the work. They even put extra hours and days for us to move back home. Everyday after work they tidy up. Even neighbours have given good feedback that they are unlike other builders who make lot of noise. Those minor things really matter when it comes to big jobs. They are fully committed to the job. I would highly recommend Vascontractors to anyone looking for big/small builds and making it a joyful experience for them.

Afrim and his team, was excellent from start to finish. He turned up on time every day, worked full days, and completed all the work within the timeframe originally quoted. He kept us informed throughout the whole project and organised all the different trades seamlessly, including tilers, plumbers, electricians, and others, which made everything stress-free for us. All building materials were planned by him and arrived in good time, which kept everything running smoothly without delays. The only challenge we had was trying to keep up with his speed and making sure materials for second fixings and other specialist bits were ready as he moved through the job so efficiently! The price was very competitive, the quality of work was great, and everything flew through Building Regulations Control with no issues at all. Reliable, hardworking, and professional — I’d definitely recommend him and would happily use him again.

Joe and his team created a fantastic driveway at one of my properties. His team were polite and friendly, they turned up on time and were there every single day until the job was done. Most Importantly the end result look brilliant, drains away perfectly, and really makes the front of that property stand out. I will be using Joe's firm for all of my driveways and patios moving forwards as i can't fault their workmanship at all. He has recently given me 2 new quotes for 2 other driveways and has beat all of my other quotations hands down.

What qualifications and experience do you have as an extension builder in Beckenham?

Will my home extension meet all building regulations and planning requirements?

What experience do you have with similar extensions in Beckenham?

Ask to see examples of their previous work, or view examples of their work on MyBuilder. Ideally projects similar to yours in scale and design. This helps you assess the Beckenham extension builder’s ability to deliver a result that meets your expectations.

Do you offer a guarantee for your work? Most Beckenham extension builders offer a guarantee or warranty on their work, often between 1 and 10 years depending on the project and materials used. This gives you assurance that any issues will be resolved after completion.
